Pyrite vs. Chalcopyrite What's the difference? Ask

2021-7-28  Chalcopyrite ( KAL-kə-PY-ryte, -⁠koh-) is a copper iron sulfide mineral and the most abundant copper ore mineral. It has the chemical formula CuFeS2 and crystallizes in the tetragonal system. The mineral pyrite (), or iron pyrite, also known as fool's gold, is an iron sulfide with the chemical formula FeS2 (iron (II) disulfide).

Pyrite and Chalcopyrite, The Fool’s Gold!! Heritage 1971

2020-2-27  Pyrite is called The Fool’s Gold because of its pronounced shininess with a beautiful metallic brass gold color. Its name is derived from the Greek word “pyr” representing fire since Pyrite can create sparks when it hits another mineral or metal. When I was little, I always find it difficult to differentiate between Pyrite and Chalcopyrite.

Heterocoagulation of chalcopyrite and pyrite minerals in

The ELS results indicated that pyrite has a positive zeta potential (zeta) up to its isoelectric point (IEP) at approximately pH 2.2, while chalcopyrite has a positive zeta up to its IEP at approximately pH 5.5. This produces heterocoagulation of chalcopyrite with pyrite between pH 2.2 and pH 5.5.

The electrical resistivity of galena, pyrite, and chalcopyrite

The sulfides galena, chalcopyrite, and pyrite are semiconductors whose electrical resistivity and type are controlled by deviations from stoichiometry and impurity content, and hence by their geochemical environment. We measured electrical resistivity, type, and the impurity content (emission spectrograph and microprobe) on small volumes of sample.
